SOLOMON OROWELL, OF SYRACUSE, NEW YORK, ASSIGNOR TO HIMSELF AND JAMES B.RUE, OF SAME PLACE.

IMPROVEMENT IN CONNECTING AND SUPORTiNG STOVE-PEPE.

Specification forming part of Letters Patent No. 58,?17, dated October9, 1866.

To all whom it may concern:

Be it known that I, SOLOMON UROWELL, of the city of Syracuse, in thecounty of Onondaga and State of New York, have invented a new and usefulImprovement for Oonneetin g and Supporting Stove-Pipe or other Pipes;and I do hereby declare that the following is a full, clear, and exactdescription of the construction and operation of the same, referencebeing bad to the annexed drawings, making a part of this specification,in which- Figure l is a perspective view. Fig. 2 is an end and side viewof the coupling.

Like letters represent like parts.

Letter a represents the stove-pipe or other pipe, letter I) thecoupling, letter 0 the flange on the coupling, letter (I the eyeprojecting from the flange, and lettere the tension-rod that passesthrough the eye d.

I make my flange and coupling of cast-iron or any other metal. Thecoupling is contracted at each end, so as to obviate any difliculty ininserting it into the pipe, as it is well known that pipe made atdifl'erent places is not always made of the same size. The couplingprojects about two inches from its center each way, which causes asupport to the pipe without the assistance of the tensionrod.

The coupling is intended to be inserted in the ends of each length ofthe pipe used and The flangeon the coupling projects above the surfaceof the coupling about one-half of an inch. When the conplin g and pipeare connected, as represented in Fig. 1 and driven together, the pipepresses against each side of the flange of the coupling, therebypreventing any air from passing in the pipe between the flange and pipe,also obviating the difficulty which frequently arises in consequence ofcold air rushing in the pipe from defects of the joints at the lengthsof the pipe not fitting together air-tight; and it is well known thatthe common manner of making pipe is by grooving, and when put together,by one length of pipe lapping over the other, will leave a space open atevery joint for the cold air to penetrate, which greatly atfects thedraft.

The tension-rod is inserted. through the eye of the flange, extendingfrom one end of the pipes to the other. On one end of the tensionrod isa cap or nut to keep the tension-rod from passing through the eye of theflange, and on the other end of the tension-rod is a thread cut, and anut fits the thread, by which the tension-rod can be drawn tight, andwhen drawn tight the pipe will sustain itself suspended without anyadditional tie above, or in any other way attached to the pipe.

What I claim as my invention, and desire to secure by Letters Patent,is-

The coupling 1), and the flange on the coupling c, and the tension-rod0, when the same are constructed, combined, and used in the manner assubstantially set forth and dc scribed.

SOLOMON OBOWELL.
